"in" clause

hello all,
i have a report A with a check box and a text item. i want to run another report B in the following page based on the previously selected check boxes.
thing is, i cant use the "in list" (comma separated values) in the query for report B because the condition:
where field in (:p12_ins) doesn't parse very well and i cant blame apex...
i hope its clear, any suggestion is appreciated.
bye guys!

Hi,
You can loop your checkbox values to collection and use it on where clause
See e.g. this post
Re: MULTI SELECT
Even post is for multiselect, same work with checkbox.
There is also other ways to accomplish what you try.

Avoiding null and duplicate values using model clause

Hi,
I am trying to use model clause to get comma seperated list of data : following is the scenario:
testuser>select * from test1;
ID VALUE
1 Value1
2 Value2
3 Value3
4 Value4
5 Value4
6
7 value5
8
8 rows selected.
the query I have is:
testuser>with src as (
2 select distinct id,value
3 from test1
4 ),
5 t as (
6 select distinct substr(value,2) value
7 from src
8 model
9 ignore nav
10 dimension by (id)
11 measures (cast(value as varchar2(100)) value)
12 rules
13 (
14 value[any] order by id =
15 value[cv()-1] || ',' || value[cv()]
16 )
17 )
18 select max(value) oneline
19 from t;
ONELINE
Value1,Value2,Value3,Value4,Value4,,value5,
what I find is that this query has duplicate value and null (',,') coming in as data has null and duplicate value. Is there a way i can avoid the null and the duplicate values in the query output?
thanks,

Hi,
Try this code.
with
t as ( select substr(value,2)value,ind
        from test1
        model
        ignore nav
        dimension by (id)

        rules
        ( ind[any]= instr(value[cv()-1],value[cv()]),
        value[any] order by id = value[cv()-1] || CASE WHEN value[cv()] IS NOT NULL
                                           and ind[cv()]=0     THEN ',' || value[cv()] END

Using a variable in "arrayTerminatedBy" clause while using a file adapter

Hi All,
How can read a file of sample shown below using a file adapter.
ABC|20081010|
2008|xxxxxxx|
2007|yyyy|
2009|zzzzzzz|
3|20081010|
first line is the header
last line is footer
middle portion is the body
'3' in the footer is the total no of record count in the body
I am able to read the header and body.
The problem i am facing is; when it is reading the footer it is treating the footer as a record in the body and is throwing an error stating - expected the format as "yyyy"
I have to use "arrayTerminatedBy" to indicate the end of the body. But that terminating field is a varying field. How can i use this variable field in the "arrayTerminatedBy" clause.
Can any one help in reading this file
Thanks in advance

See if this helps, I haven't tested it but it will give you a hint in how to achieve it. As you can see I use the startsWith command. I'm not sure how to handle your detail as it seems to start with different elements every time.
cheers

OPEN CURSOR using a WITH clause in the select query

Hi,
I am using Oracle 9i. I have a requirement where I have a REFCURSOR as an OUT parameter for my procedure. I have declared the TYPE and created the procedure.
In the procedure, I am using OPEN <cursor_name> FOR <query>;
Ideally this works in most of the cases that I have tried earlier. However, in the current case I am using a WITH clause in my query to get the results.
I need help in understanding if the above mentioned syntax would not allow me to use the WITH clause in the query.

What error do you get , seems to work ok for me on 10g

Derive found flag in SQL with where clause using TABLE(CAST function

Dear All,
Stored procedure listEmployees
==========================
CREATE OR REPLACE TYPE STRING_ARRAY AS VARRAY(8000) OF VARCHAR2(15);
empIdList STRING_ARRAY
countriesList STRING_ARRAY
SELECT EMP_ID, EMP_COUNTRY, EMP_NAME, FOUND_FLAG_
FROM EMPLOYEE WHERE
EMP_ID IN
(SELECT * FROM TABLE(CAST(empIdList AS STRING_ARRAY))
AND EMP_COUNTRY IN
(SELECT * FROM TABLE(CAST(countriesList AS STRING_ARRAY))
=================
I have a stored procedure which lists the employees using above simple query.
Here I am using table CAST function to find the list of employees in one go
instead of looping through each and every employee
Everything fine until requirements forced me to get the FOUND_FLAG as well.
Now I wanted derive the FOUND_FLAG by using rownum, rowid, decode functions
but I was not successful
Can you please suggest if there is any intelligent way to say weather the
row is found for given parameters in the where clause?
If not I may have to loop through each set of empIdList, countriesList
and find the values individually just to set a flag. In this approach I can’t use
the TABLE CAST function which is efficient I suppose.
Note that query STRING_ARRAY is an VARRAY. It is very big in size and this procedure
suppose to handle large sets of data.
Thanks In advance
Regards
Charan

If your query returns results, you have found them... so your "FOUND" flag might be a constant,...

SQL Query help ( On connect By level clause)

Hi all,
I have this query developed with data in with clause.
With dat As

ZZAI need some change on my query and I am not able to find that. So anybody can add on that or can also provide some different solution too.
Thanks!

Hi,
When you use something like "CONNECT BY LEVEL <= x", then at least one of the following must be true:
(a) the table has no more than 1 row
(b) there are other conditions in the CONNECT BY clause, or
(c) you know what you are doing.
To help see why, run this query
SELECT     SYS_CONNECT_BY_PATH (dname, '/')     AS path
,     LEVEL
FROM     scott.dept
CONNECT BY     LEVEL <= 3
;and study the results:

Query help with Model clause

Hi Gurus,
Can someone please help me out.
I've a below tables.
1) tbl_link --> this table contains information at profile level
2) tbl_summary --> this table contains summary at parent profile level derived from tbl_link table
One parent profile contains multiple child profiles and each child profile links to a code (which is B, W, G or P) and the code is linked to a category (i.e. ONL and OFL). In this case code B is linked to category 'ONL' and codes W,G,P linked to OFL category.
ONL category needs 100 points. If it don't have enough points then i need to borrow from OFL category which i'm doing and populating into tbl_summary table at parent profile level.
Now i need to insert data into tbl_link table at profile level with howmany points used, expired based on tbl_summary table. Rule is at the end of month if we add points for each profile in tbl_link table it should come as 0.

Can someone help with the query. I googled about looping in sql and came to know that Oracle has a feature MODEL to loop in SQL, but i don't have idea on using MODEL clause.
Appreciate your help!

2) tbl_summary --> this table contains summary at parent profile level derived from tbl_link table
One parent profile contains multiple child profiles and each child profile links to a code (which is B, W, G or P) and the code is linked to a category (i.e. ONL and OFL). In this case code B is linked to category 'ONL' and codes W,G,P linked to OFL category.
ONL category needs 100 points. If it don't have enough points then i need to borrow from OFL category which i'm doing and populating into tbl_summary table at parent profile level.
Now i need to insert data into tbl_link table at profile level with howmany points used, expired based on tbl_summary table. Rule is at the end of month if we add points for each profile in tbl_link table it should come as 0.

Can someone help with the query. I googled about looping in sql and came to know that Oracle has a feature MODEL to loop in SQL, but i don't have idea on using MODEL clause.
Appreciate your help!

Create Index to use Like Clause

Hi All,
I want one of my query to use a index which runs with a LIKE Clause. I have not done that before but i have heard and seen through forums that its possible to create indexes for a column with Like Clause using function based index.
Function
Request the forum users to achieve my objective. Let me list down what i have done.
Function
CREATE OR REPLACE FUNCTION RND_LIKE(P_NO IN VARCHAR2)
RETURN VARCHAR2 IS
RESULT VARCHAR2(240);
BEGIN
RETURN P_NO||'%';
END RND_LIKE;
SELECT ENAME FROM EMP WHERE ENAME LIKE RND_LIKE('A')
Here based on this function i want to create a function based index and force the same to my query. Request the forum users to help me out in this.
Thanks
Edited by: ramarun on Dec 18, 2009 9:26 PM

In the case you had there , Oracle would use an index on ename in a query if you were to type A% in the ename item on a Form. You wouldn't need a function index for that.
Here's the link to the documentation to create a function based index http://download-uk.oracle.com/docs/cd/B28359_01/server.111/b28310/indexes003.htm#i1006674

Is there a way to use dynamic built string in the "from" clause

Hi all, im having one problem and now, im not sure how to solve it easily at all... :) Is there someone that would be so kind and put a eye on it? ..thx
I have plsql proc, in which i have a list of table_names. For each of that table i need to run a query that will retrieve me a list of values and for each of that value i need to do something.
If i can be more specific about the problem -> each of that table is built as key_column, value_columns, day,starttime. For a key per table there are 4 records per hour - every quarter. Im truncating those quarters to full-quarter (minutes => 0->14 = 0min; 15->29 = 15min, 30->44 = 30, 45->59=45)
example
i get for one key and specific hour four records at 15:01;15:16;15:31;15:46 => i truncate em to 15:00;15:15;15:30;15:45..Sometimes there is a problem with the tool that is generating those data for me, and one quarter could be moved a little - so i get data like 15:01;15:16;15:29;15:46 => after i truncate the times i get duplicates in second quarter. It also can happen like this : 23:00; 23:14; 23:29; 23:44; 23:59 => totaly bad => cos the last one supposed to be as 0:00 next day, ..and 23:14 as 23:15...So...that was a problem - and solution -> i wanted to create plsql that will find those hours in each table i ve defined, and for each problem hour i make some fixes - update the bad time ...
..and i have problem - can i put an dynamic built table_name in the "from" clause?
example how i wanted to do that:
declare
     type t_objectName     is table of varchar2(030) index     by pls_integer;
     l_tableName              t_objectName;
begin
l_tableName(1) := 'tmphlrgl';
l_tableName(2) := 'tmprcfgl';
l_tableName(3) := 'tmprcfbs';
l_tableName(4) := 'tmpvlrgl';
for i in (select evtime from (select day,trunc_quarter(evtime) evtime,m_id from l_tableName(i) group by day,trunc_quarter(evtime),m_id having count(*)>1) order by evtime) loop
--some other conditions and the update...
end loop;
end;
/I cannot use the l_tableName(i) for FROM ...get an error...I was thinking to build it as dynamic sql and execute immediate into some kind of object that can store mutliple lines, from which i would in the FOR cycle get the data...But im not sure if this could be done in plsql...
thanks for your time and help..
d.

declare
c sys_refcursor;
begin
for i in 1..4 loop
open c for 'day,trunc_quarter(evtime) evtime,m_id
from ' || l_tableName(i) ||
'group by day,trunc_quarter(evtime),m_id having
count(*)>1) order by evtime';Just to high light SELECT is missing that all
OPEN c FOR ' SELECT day,trunc_quarter(evtime) evtime,m_id
          FROM' || l_tableName(i) ||
'GROUP BY day,trunc_quarter(evtime),m_id HAVING count(*)>1)   ORDER BY evtime';

Index usage in depending on where clause changes.

Hello Friends,
I need your help for one issue.
I have one query , which is using two table Say T1 and T2, where C1 is common column using which both are joined.
C1 is primary key in T1, but no index available in T2 for C1. T1C2 is the column which we want to select.
(Note that Either of table can be a Master table)
Now see the query:
Select T1C2
From T1, T2
where T2.C1 = T1.C1
Here where clause may have other conditions and From clause may have others tables as per requirements.
I want to know that, if, I change the query like following to let my query use the available index of T1.C1.
Select T1C2
from T1, T2
where T1.C1 = T2.C1
Then, Will the query use the available index of T1. and Will i get better performance. Even a little improvement in performance may help me a lot as this kind of query is being used within a where loop (so it is going to be executed multiple times).
Please advise on this..
Regards,
Dipali..

Index Usage and 'OR' Clause

I am executing following SQL but index is not getting used.
SELECT instement_id
FROM instrument
WHERE instrument_id = 100
OR 1=1
I have an index on instrument.instrument_id but it is not getting used the oprimizer is going for full table scam...
when i remove 1=1 then index on instrument_id is used...
but i am not able to understand the logic that if i add 1=1 in 'OR' Clause then why index is not getting used.
This is urgent..let me know asap...
Thanks
Rohit

How selective is INSTRUMENT_ID? Is that a primary key? Or are there many rows in the INSTRUMENT table with an INSTRUMENT_ID of 1?
Are the statistics on your table and your index up to date? How, precisely, were statistics gathered?
What version of Oracle are you using? If you are using something earlier than 11.1, it's entirely possible that you have a bind variable peeking problem.
Realistically, you would want Oracle to use two different query plans for this statement depending on the value of the bind variable. If you pass in a NULL, you'd want Oracle to do a table scan. If you pass in a value, you'd want Oracle to do an index scan. Prior to 11.1, when this statement is first parsed, Oracle looks at the bind variable you passed in and picks the best plan for that bind variable value. When you subsequently execute this statement with other bind variable values, that first query plan is used. Thus, if the first time this code was executed you passed in a NULL, it would have made sense for Oracle to choose the table scan and all subsequent executions (until the query was aged out of the shared pool) would continue to use that query plan.
Oracle 11.1 introduced the ability to have multiple query plans for the same query depending on the bind variable values that were passed in which may well alleviate the problem you're seeing.

Urgent: Performance problem with where clause using IN and an OR condition

Select statement is:
select fl.feed_line_id
from ap_expense_feed_lines_all fl
where ((:1 is not null and
fl.feed_line_id in (select distinct r2.object_id
from xxdl_pcard_wf_routing_lists r2,
     per_people_f hr2
where upper(hr2.full_name) like upper(:1||'%')
          and hr2.person_id = r2.person_id
and r2.fyi_list is null
          and r2.sequence_number <> 0))
or
(:1 is null))
If I modify the statement to remove the "or (:1 is null))" part at the bottom of the where clause, it returns in .16 seconds. If I modify the statement to only contain the "(:1 is null))" part of the where clause, it returns in .02 seconds. With the whole statement above, it returns in 477 seconds. Anyone have any suggestions?
Explain plan for the whole statement is:
(1) SELECT STATEMENT CHOOSE
Est. Rows: 10,960 Cost: 212
FILTER
(2) TABLE ACCESS FULL AP.AP_EXPENSE_FEED_LINES_ALL [Analyzed]
(2) Blocks: 8,610 Est. Rows: 10,960 of 209,260 Cost: 212
Tablespace: APD
(6) TABLE ACCESS BY INDEX ROWID HR.PER_ALL_PEOPLE_F [Analyzed]
(6) Blocks: 4,580 Est. Rows: 1 of 85,500 Cost: 2

Tablespace: XXDLD
(4) UNIQUE INDEX RANGE SCAN HR.PER_PEOPLE_F_PK [Analyzed]

Thanks in advance,
Peter

Thanks for the reply, but I have already checked what you are suggesting and I am pretty sure those are not causing the problem. The hr2.full_name column has an upper index and the (4) line of the explain plan shows that index being used. In addition, that part of the query executes on its own quickly.
Because the sql is not displayed in an indented format on this page it is a little hard to understand the structure so I am going to restate what is happening.
My sql is:
select a_column
from a_table
where ((:1 is not null) and a_column in (sub-select statement)
or
(:1 is null))
The :1 bind variable is set to a varchar2 entered on the screen of an application.
If I execute either part of the sql without the OR condition, performance is good.
If the :1 bind variable is null with the whole sql statement (so all rows or a_table are returned), performance is still good.
If the :1 bind variable is a not-null value with the whole sql statement, performance stinks.
As an example:
where (('wa' is not null) and a_column in (sub-select statement)) -- fast
where (('wa' is null)) -- fast
where (('' is not null) and a_column in (sub-select statement) -- fast
or
('' is null))
where (('wa' is not null) and a_column in (sub-select statement) -- slow
or
('wa' is null))

Cardinality estimator 2014 is off with OR in where clause

Here is my test setup on SQL Server 2014.
-- Create big table
CREATE TABLE [dbo].[Store](
Id int IDENTITY(1,1) NOT NULL,
City int NOT NULL,
Size int NOT NULL,
Name varchar(max) NULL,
CONSTRAINT [PK_Store] PRIMARY KEY CLUSTERED ([Id] ASC)
GO
CREATE NONCLUSTERED INDEX [IX_Store] ON [dbo].[Store] (City ASC, Size ASC)
GO
-- Fill with 100k rows
INSERT Store
SELECT i % 101, i % 11, 'Store ' + CAST(i AS VARCHAR)
FROM
(SELECT TOP 100000 ROW_NUMBER() OVER (ORDER BY s1.[object_id]) AS i
FROM sys.all_objects s1, sys.all_objects s2) numbers
GO
-- Create small table
CREATE TABLE #StoreRequest (City int NOT NULL, Size int NOT NULL)
GO
INSERT #StoreRequest values (55, 1)
INSERT #StoreRequest values (66, 2)
Now I execute the following query (I force the index to show statistics estimates)
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR r.City <> 55
Here are the estimates that I get (I'm not allowed to upload pictures):
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 50000
Fixing WHERE clause to use one table not two makes the estimate perfect:
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR s.City <> 55
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 89.74
Switching to 2012 compatibility mode gives estimate of 1 in both cases:
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 1
Could anyone explain the first result? I'm a bit worried about it. The fix in this case is trivial, but this problem gave us quite some headache in more complex real life queries with multiple joins.
Thank you!

But not full statistics on a field basis, just sometimes some default stats like total row count that some plans will build. Even your StoreRequest table only has one two-field index that will have a full histogram.
But I've seen SQL Server make massively bad plans on two-field indexes.
I've seen SQL Server go wrong one-column indexes, so that is not a very relevant point.
Temp tables or not, the estimate here is clearly incorrect. SQL Server knows the density of Size and City. It knows the cardinality of the temp table. The density information gives how many rows the the join will produce. The WHERE clause will then remove
a certain number of rows. With no statistics for the temp table, it does not now how many, but it will apply some standard guess.
50000 is a completely bogus number, because the join cannot produce that many rows, and SQL Server is able to compute the join with out the WHERE clause decently. (Well, it estimates 90, when the number is 180.) No, this is obviously a case of the cardinality
estimator giving up completely.
It is worth noting that both these WHERE clauses gives reasonable estimates:
WHERE r.Size <> 11 OR r.City <> 550
WHERE s.Size <> 11 OR s.City <> 550
Whereas these two gives the spooky 50000:
WHERE s.Size <> 11 OR r.City <> 550
WHERE r.Size <> 11 OR s.City <> 550

Trouble with OR in where clause

Hello,
I'm having trouble with execution speed. The problem seems to be with using OR in my where clause.
Here's the meat of the function where i_pledge_number is an input parm:
BEGIN
SELECT /*+ INDEX (pp) */ SUM(pp.prim_pledge_amount)
INTO return_amount
FROM
primary_pledge pp
WHERE
-- Get total if multiple allocations
pp.prim_pledge_number IN
(SELECT pc.pledge_number
FROM pledge_codes pc
WHERE pc.pledge_code_type = 'M'
AND pc.pledge_code = 'AC'
AND lpad(pc.pledge_comment,10,'0') = i_pledge_number)
-- Get total if single allocation
OR pp.prim_pledge_number = i_pledge_number;
RETURN return_amount;
END;
If I comment out either half of the OR statement (either the subquery or the pp.prim_pledge_number = i_pledge_number half) the function returns a value in .02 seconds. If I leave the OR in, it takes 2.764 seconds to execute?? Can someone please show me a better way (faster) to do this? I tried using nvl() around the subquery but couldn't get it to compile.
Thanks

These things are difficult to diagnose remotely, but here is something you can try....
SELECT */ SUM(pp.prim_pledge_amount)
INTO return_amount
FROM   primary_pledge pp
WHERE pp.prim_pledge_number IN (SELECT pc.pledge_number
                                 FROM pledge_codes pc
                                 WHERE pc.pledge_code_type = 'M'
                                 AND pc.pledge_code = 'AC'
                                 AND lpad(pc.pledge_comment,10,'0') = i_pledge_number
UNION ALL
SELECT i_pledge_number FROM dual)
   RETURN return_amount;
END;If that doesn't do anything (and it might well not) there are a large number of different ways we can recast this query. To save us further guessing please give us more details: execution plans, database version number, volumetrics.

Can Oracle be forced to use the spatial index for sdo_filter in combination with an or clause? Difference between Enterprise and SE?

We’re seeing the following issue: sql - Can Oracle be forced to use the spatial index for sdo_filter in combination with an or clause? - Stack Overflow (posted by a colleague of mine) and are curious to know if this behaviour is due to a difference between standard and enterprise, or could we doing something else wrong in our DB config.?
We have also reproduced the issue on the following stacks:
Oracle SE One 11.2.0.3 (with Spatial enabled)
Redhat Linux 2.6.32-358.6.2.el6.x86_64 #1 SMP Thu May 16 20:59:36 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
11.2.0.3.0 Standard Edition and 11.2.0.4.0 Standard Edition (both with Spatial enabled)
Microsoft Windows Server 2003R2 Standard x64 Edition
However, the SQL works fine if we try it on Oracle 11.2.0.3.0 *Enterprise* Edition.
Any help or advice would be much appreciated.
Kindest Regards,
Kevin

In my experience sdo_filter ALWAYS uses the spatial index, so that's not the problem. Since you did not provide the explain plans, we can't say for sure but I think yhu is right: Standard Edition can't use the bitmap operations, and thus it'll take longer to combine the results of the two queries (because the optimizer will surely split this OR up in two parts, then combine them).
BTW: when asking questions about queries here, it would be nice if you posted the queries here as well, so that we do not have to check another website in order to see what you are doing. Plus it will probably get you more answers, because not everyone can be bothered to click on that link. It would also have been nice if you had posted your own answer on the other post here as well, because my recommendation would have been to use union all - but since you already found that out for yourself my recommendation would have been a little late.
